WebThe scale-invariant feature transform (SIFT) [ 1] was published in 1999 and is still one of the most popular feature detectors available, as its promises to be “invariant to image scaling, translation, and rotation, and partially in-variant to illumination changes and affine or 3D projection” [ 2]. Its biggest drawback is its runtime, that ... WebThe paper presents a metric for visual security evaluation of encrypted images based on object recognition using the Scale Invariant Feature Transform (SIFT). The metrics’ behavior is demonstrated using three different encryption methods and its performance is compared to that of the PSNR, SSIM and Local Feature Based Visual Security Metric (LFBVSM).
